FOLDER FOB, SEWING MACHINES.

Application filed March The invention relates to new and usefulimprovements in folders for sewing Inachines, and more particularly to afolder which is adapted to form a double lap seani fell and is oftenreferred to as a feller.

An object of the invention is to provide a feller of the above type witha supporting base for upturning and inturning one of the edge portionsof the fabric sections to be united, and a scroll which inturns the edgeportion of the other section of the fabric and inter-folds the twofolded portions of the fabric sections, which scroll is made detachableand interchangeable with scrolls of other dimensions so that the fellermay be used for guiding and forming of felled seams of different widths,and also may be used for guiding fabrics of different thicknesses; thatis, the object of the invention broadly is to provide a universal doublelap seam feller which may be readily varied as to capacity.

Another object of the invention is to provide a double lapped seamfeller wherein the scroll portion may be adjusted angularly of the baseor lower portion for varying the position of one edge of the lap seamrelative to one of the needles operating to form stitches for unitingthe fabric sections.

These and other objects will in part be obvices and will in part behereinafter more fully disclosed.

i In the drawings, which show by way of illustration one embodiment ofthe inven tion Figure 1 is a plan View of a double lap scam fellerembodying the improvements;

Fig. 2 is a perspective view of the same, but showing the partsseparated in order to more clearly show the structure of each part;

Fig. 3 is a view similar to Fig. 1, but show ing a portion broken awayin order to illustrate the manner of uniting the sections;

Fig. 4 is a view of the feller from the front end thereof;

Fig. 5 a. view from the rear or delivery end of the feller; and

.Fig. 6 is a bottom plan View of the detachable and. adjustable scrollremoved from the feller.

The invention is directed broadly to a double lap seani feller which ismade in de tachable sections. One of said sections is a base platedetachably and adjustably secured to the cloth plate of the machine, andhaving an upstanding curved guiding wall for upstill lit) 1925. SerialNo. 12,838.

turning and infolding the edge portion of the lower section of fabric sothat said section is turned over the body part of the fabric section.The feller also includes a detachable scction which is provided with ascroll located relative to said guiding Wall as to receive the upperfabric section and. inturn and underturn the edge portion thereof anddirect said. interned portion of the upper section so that it will beinter-folded with the edge per tien of the lower section of the fabric.This lower section may be used with any widths of fells or thickne ":esof fabric. The scroll portion of the teller can readily be changed foraiuithcr scroll portion, so that the double lap sealn feller may thus beused for forming fcils of different widths andfroin differentthicknesses of fabric.

.lttcfcrring more in detail to the drawings, the fuller consists of abase member 1 having an upturned edge portion 2 which is bent at 3 so asto overlie the base portion 1. This part of the fellcr is carried by thesupporting bracket- 4 having elongated holes 5-5 therethrougrh, throughwhich screws may be passed for securing the feller to the cloth plate ofthe machine. i 3

Associated with this lower section of the feller or base portion is afolder scroll section which consists of a fabric supporting part 6, theedge of which is turned. downwardly at 7, thence under said. supportingpart as indicated. at 8, and thence outwardly and urnrardly at 9, andback at 10 over the supporting part so that the upper section of thefabric may pass over the support 6 and have its edge portion carriedinto the scroll and thus inturncd and under-turned. The part 8 of thescroll is spaced from the base section 6, as clearly indicated in Figs.4t and 5. The under section. of the fabric is turned upwardly andinwardly by the curved portion of the base section and the edge thereofled into the guiding space formed by this under turned part 8 of thefeller. Thus it is that the two sections of the fabric are inter-foldedso that, when they pass from this feller and are stitched together, theywill. form a double lap seam fell. This feller is adapted to be usedin'connectionwith a two needle machine r a three needle machine.

The two sections of the feller are secured together in the followingmanner: The upper section has a depending pin 11, which is adapted toenter a hole 12 in the base portion 1. This pin 11 is mounted on thelower edge of a bracket 13 which is secured to and supports the portion6 of the upper section of the feller. Said portion 6 has an openin 14therethrough. The bracket 13 is provided with a hole 15 therethroughadapted to receive a screw 16 which is threaded into the opening 17 inthe bracket 4t of the lower section of the folder. This hole 15 islarger than the shank of the screw, as clearly shown in Fig. 3. A screwdriver may be inserted through the opening Hand loosen the screw 16,which permits a limited movement of the scrollsection of the fellerswinging about the pin 11.

The purpose of this adjustment of this'upper scroll section of thefeller is to shift the left hand edgeof the felled seam relative to theleft hand needle so as to position the line of stitches formed by thisneedle closer to or farther from the folded edge of the fabric section.The entire feller may be shifted by loosening the screws which passthrough the slots 55, and thus the'curved upturned edge portion 2.shifted relative to the right hand needle. By these adjustments, thefelled seam may be shifted relative to either needle or to both needles,and in shifting the felled seam relative to both needles or relative .tothe left hand needle only, the size of the fell is very slightly varied.

' For making different sized fells, however, the upperscroll portion isremoved and another s ection having a different capacity substituted.therefor. This makes a universal double lap seam feller, which can bereadily changed for different sized seams and for positioning the lineof stitching relative to the edges of the felled seam.

The operation of folding the fabric sections is similar to that of anyfeller and, therefore, further description of the'arrangement of thefabric sections is not thought necessary, nor is it thought necessary toshow the location of the needles. It will be understood, of course, thatthese needles are adjacent the delivery end of the feller. The inventionis directed broadly to the adjustability of the feller and theinterchangeability of the sections of the feller, and not particularlyto the details of the structure of the feller or the manner of bringingabout the detachability of the parts.

It is obvious, therefore, that minor changes in the details ofconstruction and the arrangement of the parts may be made without;departing from the spirit of the invention as set forth in the appendedclaims.

hat I claim as new is 1. A lap seam feller comprising a. base por tionhaving an upstanding int urned guiding wall for directing the edgeportion of a lower fabric section and inturning the same. a scrollguiding section for inturning and undert urning the edge portion of anupper fabric section and interfolding said edge portions, said scrollsection having a fabric supporting section extending over the iuturnedguiding wall on the base portion, a bracket beneath said fabric guidingportion and secured thereto for supporting said scroll, said b acket having a portion spaced from the underside of the fabric guidingportion,means locat ed beneath said fabric guiding section for securing saidbracket to said base, said fabric guiding section having an openingtheretln'ough whereby said securing means is accessible.

2. A lap seam feller comprising a base portion having an inistandinginturned guiding wall for directing the edge portion of a lower fabricsection and inturning the same, a scroll guiding section for inturningand umlerturning the edge portion of an upper fabric section andinterfolding said edge portions, said scroll section having a fabricsupporting section extending over the inturned guiding wall on the baseportion, a bracket beneath said fabric guiding portion and securedthereto for supporting said scroll, said bracket having a portion spacedfrom the underside of the fabric guiding portion, said bracket having apin adapted to engage an opening in the base and an openingtlna'etln'ough, a clamping screw passing tl'irough said opening andthreaded into said base, said clamping screw being located entirelybeneath the fabric guiding portion, the opening for said screw beinglarger than the shank of the screw whereby when said screw is releasedsaid. scroll portion can be angularly adjusted about the pivot pin.

In testimony whereof, I ailii; my signature.
